Tecnologies de la informació (barates) aplicades a les persones amb necessitats especials

As a consequence of the lack of adequate support, many people with physical or sensorial difficulties frequently encounter obstacles to using information technologies. Today equipment and programmes exist for overcoming these barriers, but frequently they are too expensive for the economic limitations of our smaller libraries, document centres, archives, museums, etc. An inexpensive alternative can be found in the accessibility options incorporated into Windows. While these probably do not offer the best or the most adequate solutions, it can be argued that, they are an acceptable alternative, considering existing budget restrictions. This text describes the functionalities of Windows XP, grouping them according to the type of difficulty addressed (visual, motor or auditory) in order to facilitate access to the application.

Fisiologia de l'exercici en l'infant i l'adolescent. Algunes consideracions

En les edats infantil i peripuberal, les adaptacions a l'activitat física presenten particularitats específiques respecte a l'adult en els aspectes metabolics, resposta cardio-vascular i respiratoria, comportament neuro-endocrí, etc., amb diferéncies més evidents com més petit és el noi. Sembla evident que en alguns sentits el noi presenta unes respostes comparables a les de l'adult, mentte que en difereix substancialment en altres. Per aixo no és correcte considerar-lo en aquest sentit com un adult en miniatura (Borms, J., 1986). D'altra banda, cal saber en quina mesura la introducció de programes d'educació física escolar o, també en alguns casos, la participació en entrenaments intensius poden afectar les qualitats funcionals d'adaptació o alterar d'alguna forma el creixement pondo-estatural normal del noi. En aquest treball analitzem alguns aspectes essencials de tot aixo. Les consideracions que es puguin fer hauran de tenir en compte l'edat segons uns criteris biologics (grau de creixement sexual, estimació del nivell d'ossificació, dimensions corporals, etc.), més que no pas en un sentit cronologic. El fet de no atendre estrictament aquesta consideració pot ocasionar errors greus (Bar-Or, 1985).

Memòria final Catalunya i França: cors amics

Aquest projecte s'emmarca dins l'estudi i aplicació de la creativitat i la cultura mitjançant la difusió musical als àmbits de la divulgació i a l'articulació de programes de concert per part de possibles entitats que poguessin estar interessades en aprofundir i difondre al públic en general, els repertoris, autors i estils de la música coral que han estat a cavall d'ambdós territoris: Catalunya i França, al llarg de la història.

Associacionisme i esport. Perspectiva dels tècnics i les tècniques esportius en la definició d'estratègies de participació d'infants i joves immigrants

L'associació esportiva esdevé un espai on infants i joves immigrants aprenen a relacionar-se, a ser responsables i autònoms. El present article se centra en l'anàlisi de les necessitats de la població immigrada en edat escolar envers l'associacionisme esportiu, per tal d'establir directrius que en potencïin la participació. S¿han seleccionat quatre associacions esportives, en zones geogràfiques diferents, que estan duent a terme programes específics d'integració i que han estat interessades a col·laborar. L'article reflecteix l'opinó dels tècnics i les tècniques esportius en relació amb la identificació dels factors que limiten o faciliten la pràctica esportiva en contextos de diversitat cultural.

Evaluating the impact of public subsidies on a firm's performance: a quasi-experimental approach

Many regional governments in developed countries design programs to improve the competitiveness of local firms. In this paper, we evaluate the effectiveness of public programs whose aim is to enhance the performance of firms located in Catalonia (Spain). We compare the performance of publicly subsidised companies (treated) with that of similar, but unsubsidised companies (non-treated). We use the Propensity Score Matching (PSM) methodology to construct a control group which, with respect to its observable characteristics, is as similar as possible to the treated group, and that allows us to identify firms which retain the same propensity to receive public subsidies. Once a valid comparison group has been established, we compare the respective performance of each firm. As a result, we find that recipient firms, on average, change their business practices, improve their performance, and increase their value added as a direct result of public subsidy programs.

Eliciting preferences for collectively financed health programmes : the "willingness to assign" approach

Improving public involvement in health system decision making stands as a primary goal in health systems reform. However, still limited evidence is found on how best to elicit preferences for health care programs. This paper examines a contingent choice technique to elicit preferences among health programs so called, willingness to assign (WTAS): Moreover, we elicited contingents rankings as well as the willingness to pay extra taxes for comparative purposes. We argue that WTAS reveals relative ( monetary-based) values of a set of competing public programmes under a hypothetical healthcare budget assessment. Experimental evidence is reported from a delibertive empirical study valuing ten health programmes in the context of the Catalan Health Services. Evidence from a our experimental study reveals that perferences are internally more consistent and slightly less affected by "preference reversals" as compared to values revealed from the willingness to pay (WTP) extra taxes approach. Consistent with prior studies, we find that the deliberative approach helped to avoid possible misunderstandings. Interestingly, although programmes promoting health received the higher relative valuation, those promoting other health benefits also ranked highly

Educational expansion, intergenerational mobility and over-education

[eng] There is a vast literature on intergenerational mobility in sociology and economics. Similar interest has emerged for the phenomenon of over-education in both disciplines. There are no studies, however, linking these two research lines. We study the relationship between social mobility and over-education in a context of educational expansion. Our framework allows for the evaluation of several policies, including those affecting social segregation, early intervention programs and the power of unions. Results show the evolution of social mobility, over-education, income inequality and equality of opportunity under each scenario.

Organisational adaptation of multi-agent systems in a peer-to-peer scenario

Organisations in Multi-Agent Systems (MAS) have proven to be successful in regulating agent societies. Nevertheless, changes in agents' behaviour or in the dynamics of the environment may lead to a poor fulfilment of the system's purposes, and so the entire organisation needs to be adapted. In this paper we focus on endowing the organisation with adaptation capabilities, instead of expecting agents to be capable of adapting the organisation by themselves. We regard this organisational adaptation as an assisting service provided by what we call the Assistance Layer. Our generic Two Level Assisted MAS Architecture (2-LAMA) incorporates such a layer. We empirically evaluate this approach by means of an agent-based simulator we have developed for the P2P sharing network domain. This simulator implements 2-LAMA architecture and supports the comparison between different adaptation methods, as well as, with the standard BitTorrent protocol. In particular, we present two alternatives to perform norm adaptation and one method to adapt agents'relationships. The results show improved performance and demonstrate that the cost of introducing an additional layer in charge of the system's adaptation is lower than its benefits.

Components del procés interactiu que afavoreixen la formació de l'alumnat a l'educació secundària obligatòria

L'educació secundària obligatòria sembla que estigui permanentment en crisi: situacions conflictives entre els diferents agents, fracàs escolar, bullying o reiterades modificacions curriculars són alguns dels múltiples exemples que envaeixen els medis educatius i el debat social i accentuen les crítiques i les experiències negatives que es donen en aquesta etapa educativa. Certament, la secundària obligatòria té com a repte fonamental la comprensivitat, que comporta l'atenció a la diversitat de tots els adolescents en una etapa vital complicada; aquest repte educatiu i social, sens dubte, ha de tenir ombres, però també té llums en forma d'experiències reeixides que convergeixen en un millor i major aprenentatge de l¿alumnat. La recerca que es presenta en aquest article es proposa fer emergir i difondre les característiques que reuneixen les pràctiques exitoses que es donen a les aules de la secundària obligatòria. La metodologia usada per assolir aquesta finalitat essencial ha estat el recull i l'anàlisi de relats de persones de diferents trams d'edat sobre les seves millors experiències en la secundària obligatòria com a alumnes.Els diversos objectius que es pretenen amb el recull i l'estructuració d'aquestes veus es poden sintetitzar en dos: identificar les característiques essencials o components de les «bones pràctiques» i contribuir a la reflexió i el debat en la formació inicial i permanent del professorat. A partir de les aportacions recollides es pot concloure que: - A l'ESO, en el nostre context, es registren nombroses experiències reeixides per a l'aprenent. Les experiències tenen incomptables formes de concretar-se en la pràctica (en forma de projectes, plans estratègics, programes concrets de determinades matèries, etc.). - Malgrat la diversitat de pràctiques concretes, hi ha un nombre reduït de components que determinen i caracteritzen aquestes pràctiques reeixides. El nostre treball identifica aquests components i els agrupa en cinc categories que es refereixen a aspectes de metodologia, continguts, relació educativa, relació entre iguals i projecte de centre.
